Jensen XDA91RB Mono Amplifier vs Soundstream Xtreme TXP1.3500D Monoblock Amp

Buy the Jensen XDA91RB if you want app control, a 5-band EQ and a bass knob you can tune from your phone; it is the more flexible amplifier for a daily-driven sub setup. Buy the Soundstream TXP1.3500D if you are chasing maximum output into a 1-ohm load and want a subsonic filter to protect the sub. The Jensen has far more owner feedback (251 ratings at 4.0) than the Soundstream (20 at 4.6), so its track record is easier to judge. Both are Class D monoblocks with similar input flexibility; the Soundstream's edge is raw power and crossover tools, the Jensen's is tuning convenience.

  • Choose the Jensen XDA91RB if you want Bluetooth app control, a 5-band EQ and adjustable bass boost from the driver's seat.
  • Choose the Soundstream TXP1.3500D if you need big power at 1 ohm and a subsonic filter to keep a ported sub safe.

Questions and answers

Which is better for a single 1-ohm sub?
The Soundstream is built around 1-ohm loads and adds a subsonic filter, so it suits a high-output single-sub build. The Jensen also runs 1 ohm at 600 W RMS and gives you app tuning, which matters more if you want control over the sound.
Which has better sound quality?
Neither is an audiophile amp; both are Class D sub amps. The Jensen's 5-band EQ and app control let you shape the bass more, while the Soundstream's subsonic and high-pass filters help clean up low-end rumble.
Do I need the app control on the Jensen?
Only if you want to change gain, crossover, bass and illumination from your phone. If you set the amp once and leave it, the Soundstream's on-board controls are enough.
Which is more reliable?
The Jensen has a much larger owner base, 251 ratings averaging 4.0, which gives a clearer picture. The Soundstream's 4.6 comes from just 20 ratings, so treat it as promising but thin evidence.
Is the Soundstream worth stepping up to?
Step up if you run a 1-ohm sub and need maximum output plus a subsonic filter. Otherwise the Jensen's tuning features and documented power ratings make it the safer pick.
Will either fit under a seat?
The Jensen is 9.56 in wide and 2.16 in tall, which fits many underseat spaces. The Soundstream is smaller in every dimension, so it is easier to tuck away.
